“And where in the strip you can see, or anyone has mentioned, an event horizon…?” I just gave an example of the alternate instance of something hard to see but not transparent. I don’t need anyone to mention it in the strip to give an example, especially in the other case where something is hard to see. Also, a “black body” can be anything with 100% light absorption; it doesn’t have to be a black hole. I mentioned a black hole because it is the most prominent example of a black body.
YOU mentioned referring to Roget’s twice in your comments; I just wrote those off the top of my head AND I do know what pedantic means. If you don’t like my explanation or don’t understand it, then that’s just unfortunate.
Anything transparent is hard to see, but anything hard to see may not be transparent, like a black hole. If light can travel through an object, it is transparent; if light gets absorbed by the object, it is hard to see but not transparent, it’s just a black body.
If this ^^ comment doesn’t get 100 likes by the end of the day, I’ll lose faith in humanity.
